Abstract

LAS POTENCIAS DE UNA LUZ INFRARROJA Y VISIBLE SE DIRIGEN A TRAVES DE UN RECEPTACULO (14) SOBRE UNA CAMARA CCD (28) QUE RESPONDE TANTO A LA POTENCIA DE LA LUZ VISIBLE COMO A LA DE LA INFRARROJA. SE COLOCAN UNOS POLARIZADORES CRUZADOS (22, 24) SOBRE LOS LADOS OPUESTOS DEL RECEPTACULO (14) Y QUE ACTUAN SOBRE LA POTENCIA DE LA LUZ VISIBLE DE MODO QUE BLOQUEAN LA TRANSMISION DE LA LUZ VISIBLE A LA CAMARA (28) EN AUSENCIA DE VARIACIONES DE ESFUERZOS EN EL RECEPTACULO, QUE TRAS LA POLARIZACION DE LA POTENCIA DE LA LUZ VISIBLE SE DESPLAZA A TRAVES DEL RECEPTACULO. POR OTRO LADO, LOS POLARIZADORES (22, 24) TIENEN POCO O NINGUN EFECTO EN LA POTENCIA DE LA LUZ VISIBLE, LO QUE CREA UNA INTENSIDAD NORMALMENTE GRIS DE LA LUZ DE FONDO EN LA CAMARA. DE ESTE MODO, LA INCIDENCIA DE LA LUZ VISIBLE SOBRE LA CAMARA (28) DEBIDA A LAS VARIACIONES DE ESFUERZOS EN EL RECEPTACULO APARECE COMO UNA SEÑAL BRILLANTE EN CONTRA DE UN FONDO NORMALMENTE GRIS, AL TIEMPO EL BLOQUEO DE LA LUZ INFRARROJA DEBIDO A LAS VARIACIONES DE OPACIDAD DEL RECEPTACULO APARECE COMO UNA SEÑAL NEGRA EN CONTRA DEL FONDO NORMALMENTE GRIS.
